Peptely

Peptely is an independent service for checking peptide certificates of analysis (COAs) and understanding related evidence. It helps users compare a certificate with its label claim, lot number, issuing laboratory, analytical methods, and available recall records. Users can upload a PDF or image and receive an itemized result showing what matched, what raised caution, and what could not be confirmed. Checks cover reported purity, identity, impurities, lot and analysis dates, methods, laboratory accreditation, and recalls. Results use four defined outcomes—Pass, Caution, Fail, and Not verified—rather than a single trust score.

Peptely also provides a peptide library, safety and legality guides, educational articles, and information about the strength of human evidence and regulatory context for selected compounds. The service states that it does not sell peptides, provide dosing advice, or treat a certificate as proof of a vial’s contents or suitability. Commercial links may appear, but Peptely says they do not influence verification results or evidence labels. Its resources are intended to inform, not replace advice from a clinician.
